This invention relates to new' and usefui'i'mf-n provements in Windows, and` hasmore particularreference to la novel` dou-ble sash window.'

Thel invention particular-Iy' proposes an im-y proved Window sash which is characterized oyV anv outer sash frame for sllidalolyl engaging in a window frame, and an inner sashframev hingedly connected with the' outer sash frame for closing the opening of the outer sash frame.l

Itis proposed that-the new and improved' Win-v dnwy sashV beused in conjunction with' counter-` weights. orf other syst-,emsl now generally used" orknown of: for reducing the.` eiort required: in moving the window sash. f

The invention. contemplatesnumerousv embodiments of improvedv window sashesl. Specifically, it isr proposed to wary/'the hinged; arrangement off the inner sash the outer sash, for" example, byz pivoting' the inner: sash frame at one side,v orat the otherside, orati the top, or'at they bottom,y or intermediatel of' its ends,n etc.;

The invention. also proposesza 'noifel-y means for securely holding' the sash: trames together to pre vent'rattling;

v.mothetcobject off 'the` invention .is the 4coristruction` of a. device as'fmentioned" which isi ple; and durable and? which may be manufac turede and sold .at a` reasonable cost.

For iurther comprehensioi-iy of tt'lef. invent-ion,A

and of the objects an-dadvantagesthereof-,refe enence will be: had tol the following; ydescription andaccompanying drawings, andftoi the appended claims in which thesvarious novel features ofA` the invention are more particularty setuihrtl'r` In the accompanying drawings forming av maA teri'al parteithis;disclosure:`

Fig. 9 is ain elevational? view of a-Window' con-I weight's (not rshoxlvn or other mechanism to re'- duce the effort required inmaving` them. Each sash it comprises an' outer sashfiame- I2's1idab1y mounted in said window frame lill, and an inner sash trame. |34. for closingl the opening of the. outer sash frame 12'.' The inner vsash frame- M is: liir-rg'edlsrconnected Withthe outer sash frame t2' byfhinges. Iii along one of their adiacent sides.

The sash, frames t2 and" M are associatedr with,

vent rattling. This means includes several? domes-'shaped memioers'` I6 slid'ably mounted on one ot the sash frames and engageablewith-voorhv responding recesses.` on the adiacent sash frame'.

'3U-i particularly,,each Ydome-shapedy member i6 is slidably mounted a1. casing YIt set into one ofthe sasl'n frames. A1 spring i8 is housed? within the. casing4v M? and normally resilientltzA urges the dome-shaped member I'Bf outwards;

The operation ofthe invention maybe understood" from thev following.

'I-'iieA window sashes Il when in their clfosed position may be moved upwards and downward-'s in the conventional Way. If for any' reason it is desired?. toA conveniently reach tlli'eI outer faces of the panes: included in the Window sash it is merely-f necessary to= openV the? inner -sashy frame f4?. In Fig. 1 the upper'sashis' shownin its-"closed position, while the-lower'one is shown its inneriiirame partiaH-y swung open.

lin Figs. 31- 8 inclus-ive a modi-"iisd form of' the inventionL has been disclosed which basi'callifl is simiiar toY they first form off' the invention, but

differs in several respects. Inthe rst place each inner sash frame I4 is hingedly connected with the outer sash frame I2 by hinges l5 positioned along the bottom edge portions of these frames. In the second place, each outer sash frame l2 has its side arms formed of two separate sections 20 and 2| in end alignment with each means ffor securely holding them together tor` pre-f which itm'ay beturned. A spring 29 Vis housedV Within alcavity-D in oneof the sections, namely, the section 2|, and engages against'the section 20 for resiliently urging the sections apart.

2,406,513 A Y 11j-Tf The top edgevof the inner sash frame |4fis7 formed with a groove 3| extending its full length. Theouter sash frame I2 is provided with a tongue 32 engageable into the groove 3|.?

'Ihe operation of this form of the invention is similar to the prior form. When the inner sash' frame is closed in relation to the outer sash frame Ythe windows may be moved in a conventional manner. If itis desired to open the innersash frame I4 it is first necessary that the knobs 128 be turned, to turn the cams 26 from their locking positions, illustrated `by Fig. 4, to their openl positions, illustrated by Fig. 5. kIn the latter position, the sections 2li and 2| of thev side armsof Y the outer frame I2' are slightly separated. This separation will move the tongue 32 out .ofthe groove 3|. Now the inner sash frame isfreeto be hinged open. i

with its'inner sash .frame partially swung open; The upper window' sash is illustrated with its sash frames closed in relation to each other. Whenv the tongue 32 and groove 3| ofthe sash frames engage each other the sash frameswill be4 securely held'against rattling. Y

In Fig. 9 still another modified form of the invention is disclosed, whichis very similar `to the -form shown in Fig. 3, distinguishing however, in the fact that-the outer sash frame |2"- has its side arms and 2|" `of separate sections separated above its horizontal center..1 VThe'inner sash` frame 4 is hingedly or pivotallyv mounted within the outer sash-frame I2 by pivots 35 at the sides.

In other respects this form of the invention is identical tothe previous form and like partsare indicated by like reference numerals.

In Fig. 10 still another form of the invention is similar to that previously shown and like reference numerals identifylike parts in each of the several views.

' In Fig. 11 another form of the invention has been disclosed which is verysimilar to the one shownvin Fig. 1, distinguishing merely in thefactv that the outer sash frames |2agare formedwith'V` central vertical arms 38 dividing them into two panels each. The inner sash frame'is in lthe nature of vseparate inner sash frames I4a hingedly connected at their outer sides bythe hinges I5` with the inner sash frame. These inner sash 1 j 30 In: Fig. 3 the lowerfwindow sash is illustrated frames |4a close the openings of the outer sash frame.

In other respects thisvform of the invention isr similar to that previously shown and like reference numerals identify like parts in each of the several views.

In Fig. 12 a, reinforcing bolt 40 is shown in the bottom portion of the outer sash frame |2". `A slot 4| Yis formed to be extending inwardly from the edge 42` of 'the outer sash frame I2". This slot is adapted to receive a nut'43 which engages overV the threaded end of the bolt 40. v When this nut is secured on thebolt, it reinforces the windowusash and prevents the windows from sagging,

warping or loosening on their joints.

While I have Yillustrated and described the prelferred.embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the -scope of the invention fined in theappended claims., I

Having thusv described my invention, what IKV 'claim as new and desire to secure by United States Letters Patent is: l v V 1. In a window, a window sash, ycomprising an outer sashframe for sliding in a windowframa' an inner sash frame for closingtheopening of said outer sash frame, and'meansfor'hingedly connecting said inner sash frame with said outer sash vrframe, said outer sash frame having-its side arms formed of separate sections in endalign-x ment with each other, and means for. selectively drawing said sections together orslightlysep-i arating the sections for clamping theinner sash frame within the outer sash framex" I i 2.
